Patent EP-0683841-A1 (EP)
Inventor: STRICKLAND JAMES K
IPC: E03F5/02
Filed: 1994-02-10
Abstract: A plastic liner (200) for protecting a concrete manhole interior surface from corrosion wherein the liner includes provisions for creating a strong interlock between the liner and the interior surfaces. A side of the liner which includes the provisions has a plurality of raised hollow projections (206, 208) with spaced sections. The mechanical lock is created when concrete is poured against the side of the liner with the projections. The concrete at least partially enters the hollow portions (210) and fills the space (222, 224) between the projection sections. The projections (206, 208) also intersect to enhance the mechanical interlock by preventing bulging. Liner sections cover essentially all of the manhole interior surfaces. Forming the liner by rotationally molding the plastic and cutting gaps (214) into the projections (206, 208) is also disclosed.

Abstract: A hybrid digital/analog video recorder prevents both analog and digital copying. The recorder (including a digital tape deck) inputs and outputs both analog and digital video signals. At the analog input, a detector detects conventional copy protection in the analog input video, and in response disables recording thereof. At the digital input, a first detector detects anti-copy bits present in the input material and in response prevents recording. A second bit detector detects serial copy prevention scheme bits, and in response adds an anti-copy bit to the input digital stream, preventing later copying of such material. When another bit detector detects anti-copy bits present in the playback digital data stream prior to conversion to analog, an analog copy protection signal modifies the output analog signal, inhibiting copying of the output signal. In another version, a specially adapted video recorder or playback device copy protects video source material which for technical reasons is not copy protectable. A copy protect "flag" is provided in a predetermined location in the video signal to be protected. The video recorder or playback device,, upon detection of the flag at playback, modifies the output standard (NTSC) video signal with a conventional copy protection process.

Abstract: A process and apparatus for the molecular oxygen oxidation of a secondary alcohol such as isopropanol to hydrogen peroxide is provided. In one embodiment, exothermic heat of reaction is removed by vaporising part of the reaction mixture, condensing and returning the resulting vapors and adding a ballast gas prior to condensation. In another embodiment, the net oxygen requirement is provided by injecting molecular oxygen into reaction liquid which has been removed from the oxidation zone, and circulating the combined mixture back to the oxidation zone. In yet another embodiment, the oxidation is carried out in two zones with the total oxygen being fed to, and the hydrogen peroxide product being recovered from, the second reaction zone. Apparatus for the reaction comprises a preferably spherical reactor (1) having a first annular reaction zone (4) surrounding and separated by a cylindrical baffle (2) from a second central cylindrical reaction zone (3). The baffle has holes to permit liquid flow from the first zone to the second zone.

Abstract: Disclosed is an apparatus for controlling the attitude of a radio-controlled helicopter, which is equipped with elevator, aileron and rudder servomechanisms. It comprises three single-axis gyroscopes (10) each having its axis aligned with the pitch-reference, roll reference and yaw-reference axis to provide signals representing the instantaneous pitch, roll and yaw angular velocities at their output terminals; and control means (CPU) responsive to the pitch-angular, roll-angular and yaw-angular primary control signals from an on-ground transmitter, and to the signals from the gyroscopes for providing pitch-angular, roll-angular and yaw-angular secondary control signals to the elevator, aileron and rudder servomechanisms respectively. 
     The control means is so designed that: a PID control may be effected on each controlled variable until a predetermined threshold value has been reached, and then a PD control may be effected on each controlled variable until the end of the required control. The predetermined threshsold value at which the PID control is switched to the PD control mode represents a relatively narrow, but uncontrollable variation range in which the attitude of the helicopter depends on uncertainties. 
     A helicopter equipped with an attitude-controller according to the present invention is guaranteed to be free of an adverse effect caused by uncertainties such as unexpected effects on other controlled variables caused by controlling a selected conrolled variable or the varying condition of wind, accordingly facilitating the radio-controlling of the helicopter from the on-ground transmitter.

Abstract: An adsorption type air cooler which has a high coefficient of performance and can be stably operated over a long term. When a refrigerant vapor having evaporated by heat exchange with a load water in a refrigerant storage tank serving as an evaporator is adsorbed by an adsorbent heat exchanger, a cooling water for removing heat of adsorption is conventionally caused to circulate at a constant temperature and a constant flow rate normally determined by circumstances while according to the invention as claimed in claim (1) a temperature and a flow rate of the cooling water for removal of heat of adsorption are artificially controlled depending upon a cold output of the load water by making use of a cooling water heated after removal of heat of adsorption or a heat source water. The invention as claimed in claim (1) is an invention, in which a refrigerant storage tank and a load heat exchanging section are provided separately from each other, and a load cooler is provided for causing heat exchange between a refrigerant liquid supplied from the refrigerant storage tank through a pump and a load to cool the load while evaporating a part of the refrigerant so that gas-liquid separation is effected by returning to the refrigerant storage tank the refrigerant liquid having performed heat exchange in the load cooler, a refrigerant vapour and a mixed fluid thereof. As the refrigerant storage tank and the load heat exchanging section are provided separately from each other, an evaporative latent heat of the refrigerant is utilized independently of temperature change in the refrigerant storage tank to effect heat exchange between the refrigerant and the load whereby a load heat of a constant temperature can be obtained.
